Subway conductors told to be more assertive closing doors on riders to reduce delays. “What’s causing the delays is their incompetence,” one commuter said.

More than five million riders crowd into New York City’s subway on an average workday, and officials say some of them are making everybody late.

At the 34th Street-Penn Station stop, Frank Gallagher thrust his foot between the closing doors of an uptown 2 train on a recent morning and wedged his way inside. “I made up my mind I was going to catch that train,” said the 57-year-old entertainment industry union rep. “I’m five minutes late as it is.”
